Abstract

L'invention concerne un matériau isolant électrique et/ou une résine d'imprégnation destinés à l'isolation de bande d'enroulement, une substance isolante formée à cet effet par durcissement ainsi qu'un système d'isolation, par exemple un système d'isolation pour une machine électrique tournante, en particulier une machine moyenne ou haute tension. L'invention concerne un matériau isolant, c'est-à-dire une composition pour un mélange durcissable, qui forme une substance isolante, laquelle, lors du fonctionnement dans les mêmes conditions, permet d'obtenir la durée de vie en fonctionnement jusqu'à 8 fois supérieure à la durée de vie en fonctionnement des systèmes conventionnels. Ceci est attribué à la combinaison symbiotique de la substitution de la résine époxy conventionnelle, au moins partiellement, par des composants formant une structure SiR2-O avec des nanoparticules inorganiques et un additif de frittage, qui provoque la fusion des nanoparticules dans la résine de base.
